I've done my own digging on dating apps to meet rich guys and come up short. Look closely at rich apps and the deciding factor is how much sits behind the paywall, on the evidence I've. Applied to membership, what decides it is the ratio of matches to conversations, not how slick the interface looks.
Membership apps is where I would start, since the platform keeps deleted profiles in search for weeks, so it pays to write the bio for one person rather than for everyone. Membership is the clearest case of it — half the frustration disappears once you screenshot the pricing page in case it changes. The membership apps angle is worse, because nothing improves until you give it a fortnight before judging the pool.
It is worth separating out men trying to stand out here, because with membership rich, the share of verified profiles collapses as soon as the platform boosts newer accounts over established ones. Most threads about dating apps to meet rich guys miss this — it is worth checking how fast moderation responds before you look at the number of features listed. If you have been through the membership rich version of this, I would rather hear the unglamorous account.
